Question

P$\times$ Q means P is the sister of Q;
P+Q means P is the father of Q;
P-Q means P is the mother of Q.
Which of the following means S is the aunt of T?

• A. T$\times$ M+S
• B. S+T$\times$ M
• C. S$\times$ M+T
• D. S$\times$ M+R-T

Answer 1

The correct option is C S$\times$ M+T

If S is to be aunt of T, S must be a female and S must be one generation over T.

Here, option(A) and (B) are eliminated because in option(A) the sex of S is uncertain while option (B),S+T means S is the father of T.

S$\times$ M means S is the sister of M and M is the father of T.It means, S is the aunt of T.

So,option C is correct.
